NPC-300 | Disposable Medical Pressure Sensor


The NovaSensor NPC-300 is a Disposable Medical Pressure Sensor specifically designed for use in disposable medical applications. The device is calibrated and thermally compensated with a digital I2C output incorporating a signal conditioning integrated circuit. Wetted materials have been tested in accordance to ISO 10993 and USP Class VI Specifications for protracted duration of contact up to 30 days.

NPC-300 is fabricated in a Class 1000 Clean Room to minimize possible sources of contamination. Programmable signal conditioning is utilized for final compensation and calibration. Total Error Band (TEB) is maintained at ±5.5% within the defined compensation range.

The method of assembly draws from well-established manufacturing techniques used in the electronics industry to produce a quality product in a miniature package (5.6mm x 3.4mm x 2.3mm) and is available in tape and reel packaging for automated assembly.
